8 Claims.

My invention relates in general to books having loose, removable leaves, which may be inserted in and removed from the cover or binder, individually or in a bunch as a unit. By my improvements 'I provide a structure which is easily operated, is strong in its make up and presents a neat and finished appearance, the binding or tie devices for the leaves being entirely concealed from view when the leaves are put in place and the book laid open. The novel structure of my improved book, makes it available for use in practically all classes of loose-leaf books, and it is well adapted for useas a book for exhibiting in the trades, fabric or cloth samples which may be mounted on the leaves in the usual manner. It also possesses other useful details of the structure, which will hereinafter appear in the description of the same.

I have illustrated a type of my invention in the accompanying drawi wherein:

Figure 1 shows a perspective view of a looseleaf book embodying my improvements; the lids of the cover being shown. as laid open sufficiently to expose the bound leaves, one of which is shown with a sample of goods attached thereto.

Figure 2 shows an enlarged perspective view of an end portion of the book, with the parts assembled in their binding relation, except that one of the folding flaps is raised to show how it conceals one end of the binding device or post.

Figure 3 shows an enlarged cross-sectional view of the book with the leaves bound therein and the lids of the cover spread open.

Figure 4 shows a somewhat reduced view of the parts shown in Fig. 2, but with the parts unfolded and in positions to show how they are related to each other in their operation.

Fig. 5 shows an enlarged perspective view of the clip for covering and reinforcing the end of the binding parts.

Referring to the drawing, in which like numerals of reference designate like parts throughout, the cover comprises a pair of lids or boards 1 and 2, which are hinged or united to the central back piece 3, so that they may be swung or flexed thereon in opening and closing the book.

The means for attaching the device to the inside of the cover, comprises oppositely arranged members 4 and 5, spaced apart in parallelism to receive therebetween the inner edges of the looseleaves 6, when bound therein. These attachingmembers are yieldingly secured to the cover along the length of the back piece 3, and may be swung or flexed on their mountings. The free edge of member 4, is provided with a flap or wing 7, which folds inwardly against the inner face of said member, and the free edge of member 5, is likewise provided with a flap or wing 8, which folds against the outer face of its member 5, said flaps folding in the same direction.

Theattaching means comprising the members and their flaps, may be made of any suitable material in order to provide means for carrying and concealing the tie or binding posts or parts 9, which pass through the perforations 10, in the leaves 6, each post 9, having one end mounted in the flap '1, and the other end in the member 5. To accomplish this construction and arrangement of the members and flaps, various different ways may be adopted, though I have here shown but one way of making these parts in a simple way by use of a flexible fabric such as that used in binding books. This is done by employing a sheet of flexible material 11, and doubling it on itself along two parallel lines of its length so as to provide pockets or folds 12 and 13, and attaching its long edges 14 and 15, by adhesive substance, to the respective cover lids 1 and 2, and attaching its central portion 16, by adhesive substance, to

v the back piece 3. The edges 14 and 15, are overlapped by the fabric 17, which is secured to the lids by suitable adhesive, and likewise to the edges. In order to stiffen and reinforce member 4, I insert in the pocket 12, a stiffening piece 18, and to likewise stiffen the flap 7, I insert in another part of the pocket the stiffening piece 19, the said pieces being spaced away from each other so as to provide a flexible place at 20, between them for the purpose of folding the flaps on their members 4 and 5. If preferred, metal may be used for the embers 4 and 5, and the same hinged to the ack, and also for the flaps 7 and 8, and the same hinged to the members. stiffening pieces 21 and 22, are inserted in the pocket 13, and are spaced apart to afford a flexible place 23, for the flap 8, to swing on. In each case, the stiffening pieces are glued in place within the material forming the pockets, and the material'is glued together at the flexible or hinge places 20 and 23.

The tie or binder posts or parts- 9, upon which the loose leaves are strung by means of their perforations, are arranged one near the top and the other near the bottom end of the book and they are constructed and arranged alike. Each tie post consists in a cylindrical tube having its inner end provided with a fixed enlargement or head 24, while its outer end is provided with a detachable slotted head 25, having a screw-threaded stem 26, which screws into a corresponding thread in the interior of the post, as shown in Figure 3.

The tie or holding posts for the leaves are mounted in place, by swinging upwardly the flap fixed head or flange 24, in contact with the inner face of said fiap. The flap is then folded inwardly upon member 4, as shown in Figs. 2 and 3, and after the leaves are strung on the post, its free end is then passed through the hole 28, in the attaching member 5, and the screw head 25, is screwed onto the post, so that the head thereof bears against the member 5,-causing the latter to press snugly against the bunch of leaves and bind them in place between the attaching members. When'thus bound in the book, the leaves are securely held in place and may be easily opened as shown in Fig. 1, and the heads of the binding or tie posts are concealed within the folds of the respective-fiaps "I and 8, as shown in Figs. 1 and 3, so as to present a neat and finished appearance when the book is opened. Any desired number of the tie posts may beused and instead of the fiaps being continuous from top to bottom of the book, they may be made separate, one for each post, likewise the attaching members may be made into separate ones, one for each binding post, but the continuousstructure gives a more finished appearance to the book. e

At both the top and bottom ends of the binding means, I provide a U-shaped clip 29, the legs 30 and 31, of which are formed with: perforations 32 and 33, respectively, for receiving the tie posts 9. The closed end of theclip is covered with suitable fabric 34, preferably the same as the fabric 35, which is glued to theouter face of the cover lids 1 and 2, so as to match the same in appearance and enhance the finish of the book. These clips are put in place before the tie bolt or post 9, is inserted in flap '7, by placing the leg 31, against the inner face of the flap, so that the perforation 33, registers with" the hole 27, in the flap, and with the other leg 30, disposed to the outer side of the flap, as shown in Fig. 4. The tie post is then passed through both the holes 33 and 27, and the fiap then folded down, as shown in Figs. 2 and 3. After the leaves are strung on the post, the other clip leg 30, is placed against the adjacent leaf and the post then passed through the hole in the attaching member 5, as hereinbefore described. The screwhead 25, is then attached to the post so as to bind against the outer face of the member 5, and thus hold the parts securely together, and the flap 8, is folded down. These clips serve to hold the extreme outer ends of the attaching members together and thereby reinforce the' structure and they also serve to cover the ends of the loose leaves where they are bound in place, and they give the book a more finished appearance than if the leaves were left uncovered at such places, and together with the continuous attaching members and their flaps, they provide housing for the. inner ends of the bound leaves.

In order to remove the leaves, the fiap 8, is raised and the screw heads 25, are unscrewed from the posts, then the attaching member 5, is disengaged from the posts by swinging it outwardly, then the leg 31, of the clip, is disengaged from the posts, and the leaves are free to be removed from the posts.

In using the book for a sample book for fabrics, the samples of fabric are pasted on the leaves as indicated at 36, in Fig. 1, but in some Cases,

the goods themselves may be bound in place by the means described, without the use of leaves of other material, and as is now the practice in making sample books of cloths for clothing. It will therefore be understood; that the word leaf may mean either of the two described things.

By virtue of my. novel construction and arrangement of the leaf holding or tying means and the means for mounting the same and attaching it to-a cover or the like part, such means may be used with various different forms of loose leaf binders and maybe made of metal, or part metal and part of other material. I wish to be understood as not limiting my improvements to the specific constructions of the various different parts thereof, as it is manifest that modifications may be made in the same, without, however, departing from the spirit of the invention.
